1'0 aZ Z whom i may concern.- I

Be it known that I, WILLIAM R. WILLIAMS,

a citizen of the United States, residing at,

,and co-operating parts disassembled to show 55 Philipsburg, in the county of Centre and State: of Pennsylvania, have inventeda new and useful Hinge-Seating Device, of which the following is a specification. I My invention relates to hinge seating or gaining machines, and it has for its object' to to provide an efficient and durable device.

provided with width and depth cutting chisels so connected as tobe operable bya single 1ever, in addition to a feeding device wherebythe carriage upon which such chisels are r 5 mounted is moved longitudinally to form the desired length of seat or gain, said seating devices being operated by the lever controlling the cutting devices.

A further object of my invention is to provide simple and efficient means for adjusting the movement and throw and the location of the parts to vary thelength, width and depth of the seat or gain to adapt the same to receive hinges of different sizes; and means for adjustment to take upv wear, lost motion, duo.

- Further objects and advantages of this in: vention will appear. in the following description,and the novel features thereof will be particularly pointed out in the appended claims. I

In the drawings: Figure lis a perspective view of a hinge-seating machine embodying my invention, applied in the operative position to the edge of a door. Fig. 2 is a simi- 3 5 lar View, looking at the rear side of. the machine. Fig. 3 is a rear elevation, partly broken away, to show the feeding mechanism for the carriage. Fig. 4 is a plan view, partly broken away to show the push-bar and trip device for actuating and releasing the rocking lever which carries the depth-cutting chisel-block, the parts being shown in the po sitions which they occupy when the widthcutting chisel is extended and at the limit ofits forward movement. Fig. 5 is a similar view, showing the parts in the positions which they occupy when the width-cutting chisel is retracted and the depth-cutting chisel isextended, and just before 'thetilting lever is released by the trip. Fig; 6 is a similar view, showing the parts in thepositions Serial No. 495,412. (No model.)

which they assume afterthe'trip has released the rocking lever. Fig. 7 is a detail View, in perspective, of the depth-cutting chisel-block the means for taking up wear in the depth cutting chisel. f

. Similar numerals of reference indicate cor- .respondin g parts in all the figures of the drawings. i 1 designates the frame by which the machine embodying myinvention is secured to the article to be gained, and it consists essentially of a bed 2, adapted to bear against one side of said article or object, and a parallel bar 3, which is adapted to be arranged upon the opposite side of said article and carries an eccentric locking lever 5, whereby the frame is secured in placea 6 represents an adjustable bearing-strip, which is arranged contiguous .to the inner surface of the bar 3 and is provided with terminal guide-pins 7, fitted in. guide-perforations 8, in said bar, and the eccentric or cam locking lever bears against thecenter of this strip and forces it against the surface of the door to avoid marring the, door. Mounted slidably upon this frame isva carriage 9, provided with guides 10, engaging the ways 11,

andfulcrumed uponthe carriage is the op erating lever 12, carrying a spring-actuated feeding pawl 13, which is arranged to engage a rack 1 1, upon the bed. The carriage is provided, furthermore, with a spring-actu ated locking pawl 15 to engage .the'rack and .85 hold the carriage stationary during the operation of the cuttingchisels:

16 represents the width-cutting chisel slide which is fitted for reciprocation in a guide 17 upon the perpendicular portion 18 of the carriage, and the operating lever, is arranged to convey motion 'to the said slide by means of the slotted connection, comprising a pin 19 on the slide, fitting in a slot 20 in the lever.

Upon a bracket 21, forming a part of the 5 carriage, is fulcrumed a rocking or tilting lever 22, which is pivotally connected .at its front end to a depth-cutting-chiselblock 23, mounted upon a dove-tailed guide 24,.car-

ried by said bracket; and connected at its roev rear end to the width-cutting-chisel slide by means of a push-bar 25, whereby, as the slide is retracted, the tilting lever is operated to move the depth-cuttingchisel block inward or toward its work. The connection between the push-bar and the tilting lever consists of a trip mechanism to cause the release of the lever before the operating lever reaches the limit of itsmovement; and this trip mechanism consists of a shoulder 26 upon a pushbar, which is arranged to engage a transverse pin 27, located in the bifurcated end of the tilting lever, a retaining spring 28 being carried by the push-bar with its free end arranged adjacent to the shoulder 26 to prevent the accidental disengagement of the shoulder 26 and pin 27. At the extremity of the push-bar is arranged a trip finger 29, which is adapted to engage a stop 30, in the bifurcation of the tilting lever just before the operating lever reaches the limit in the direction opposite to that indicated by the arrow in Fig. 1, said engagement of the trip finger and stop being shown clearly in Fig. 5. Therefore, as the width-cutting-chisel slide continues its outward movement the pressure of the trip finger upon the stop 30 causes the pin 27 to repress the retaining spring 28 and allow the pin to pass between the spring and the push-bar, thus releasing the tilting lever and allowing the return spring 21 to repress the rear end of the tilting lever and remove the depth-cutting chisel-block from the gain, as shown clearly in Fig. 6. finger is preferably formed of a steel plate spring, and is provided with an adjusting screw 32 whereby its projection from the pushbar may be varied to cause it to engage the stop at any desired point during the stroke of the operating lever to vary the throw of the depth-cutting chisel-block, and thus vary the depth of the cut formed by the chisel carried by said block. The depth-cutting chisel 33 is fitted in a seat 34 in the chisel block, and a bowed clamping plate 34: is arranged in contact with the outer side of the chisel and is secured in place by means of a set-screw35, which extends through the chisel, theopening 36 in the chisel for the reception of said set-screw being elongated to permit of longitudinal adjustment of the chisel. An adj usting-screw 37 is arranged in the end of the chisel-block and impinges against the extremity of the chisel, whereby the latter may be adj usted to take up wear. The bracket 21 is adjustably mounted upon the carriage to permit of the adjustment of the depth-cutting devices to suit difierent widths of gains, said adjustment being longitudinal with relation to the movement of the width-cutting chisel slide and being accomplished by means of a slot 38 and set-screws 39, which engage the body-portion of the carriage.

The throw of the operating lever in the direction indicated by the arrow in Fig, 1, is limited by means of the adjustable stop 39, which impinges against the body-portion of the carriage, and which may consist, as shown The trip in the drawings, of a screw. By means of this adjustable stop the extent of movement of the width-cutting chisel slide is regulated to form the desired width of cut.

The operating lever is connected,by means of a slotted link 40, with the locking pawl 15, the slot 41 in said link being engaged by the pin 42 on the lever, whereby the lever operates independently of thelocking pawl until after the tilting leverhas been released from thepush-bar by means of the trip mechanism above described, when said locking pawl is withdrawn from engagement with the rack and immediately thereafter the feeding pawl engages the rack and moves the carriage forward in position to form the succeeding cut. The length of the gain or seat is controlled by means of the adjustable gages 4:4,secured to the bed of the frame and adapted to be engaged by a stud 45 on the carriage. These gages are slotted and are held in their adjusted positions by means of set-screws 46.

The depth of cut of the widthcuttingchisel is regulated by the'set-screws 47 carried by the frame and adapted to impinge against the edge of the door or other object to be gained.

Thus, the depth of cut of the width-cutting chisel is regulated by the placement of the frame, or the position in which it is arranged upon the door.

The operation of the various members com-' prising the improved hinge-seating device will be readily understood from the foregoing description, and it will be seen that the various parts are adjustable tovary the length, width and depth of the gain to fit a hingeleaf of any ordinary size. It will be understood, furthermore, that the width and depth cutting chisels, and the feeding mechanism are operated by a common lever, the depthcutt-ing lever following the width-cutting lever in movement and being retracted by the release of its tilting lever before the width cutting lever reaches the limit of its backward stroke, in order to allow time for the locking pawl to be disengaged from the rack and the feeding pawl to advance the carriage a step in the direction of the length of the seat or gain.

Various changes in-the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is- 1. In a hinge seating or gaining machine, the combination of a width-cutting chisel slide, means for operating said slide, and a depth-cutting chisel block, of a tilting or rocking lever connected at one end to said block, connections between the said lever and the slide, and a trip mechanism to release the lever near the limit of the backward movement of the slide, substantially as specified.
